Bed, Bath and Beyond offers a few bed accessories designed to control bedding from moving to another zipcode as you slumber. First is the Sleep-Snug, a set of 4 plastic clips that hold your fitted sheet in place onto the mattress to create a snug and smooth finish for your bedding.
But what about your overheated noggin' during these trying summer nights? Blasting a fan or air conditioner all night is both expensive and sometimes detrimental to the health. How about a Chillow, a "thin, very soft, medical-grade, non-electric thermoregulating device"? Basically a pillow insert that can be used as-is or after cooled in the refrigerator for even more effective cooling effect. Looks like a promising item to help keep the tossing and turning reserved for romantic effect, and not because you're dreaming you've become a human crepe.
